Writer Mason Cross was pleasantly surprised when, years after seeing the film PSYCHO, he found the book just as enjoyable. And that Hitchcock hadn’t played fast and loose with Bloch’s incredible thriller . . .

Award-winning thriller writer R. J. Ellory invites us to pause and ask ourselves: what would really scare us? For it may have been his own answer to this question that led Alfred Hitchcock to make his most successful film.

Film adaptations are difficult things to get right. Depending on the quality of the original material, sticking closely to the text does not always make for an interesting piece of cinema. Hitchcock for the most part chose to use the novels he filmed as more of an inspiration, rather than produce a faithful representation of the book.
